Zach is filling his dogs bowl with water. Is it reasonable to say that Zach will need about 4 gallons of water?
xeze [42]
No, that would not be reasonable to say.

If you were filling some buckets, you could say 4 gallons, but we’re talking about a bowl and at the most that will take just a few cups.

I hope this helps and please let me know if you need further explanation!
